The arrangement of the exhaust turbo-blower [aggregates may be so chosen according'to the invention that either the exhaust gas turbines or else the supercharging blowers are situated at the exterior ends of the respective aggregates adjacent to the face ends of the engine.
In the accompanying drawings two constructional forms of the invention are shown by way of example 'only, in which Fig. 1 shows a cross-section of an internal combustion engine according to the invention,
Figs. 2 and 3 each show a corresponding plan view of a twelve and a sixteen-cylinder engine respectively, and
Fig. 4 is a vertical longitudinal section'through the axis of the internal combustion .engine.
In all the figures of the drawings like characters represent like parts.
By I, 2, 3, l, 5, 6, l and 8 the combustion cylinders of one row of the engine are designated and by I, 2, 3'. 4', 53.6, I and 8' those of'the other row of the engine.
The internal combustion engine comprises pistons 9 and 9' respectively, piston rods l0 and M respectively which cooperate with a crank-shaft ll. i2 refers to the inlet and I3 to the exhaust valves, these valves being situated in the cylinder heads in the engine and actuated by means of control shafts i4 and I4 respectively through the intermediary of tappets i5 and i5 respectively. Water cooled jackets surrounding the cylinder walls are designated by numerals 25, 25'. The engine is provided with two exhaust turbo-blower aggregates i6 and II which are disposed within the open portion of the V-shaped part of the engine at the face ends of the latter.
The numerals i8 and i9 represent the exhaustgas turbines'and 20 and 2! the blowers driven thereby. The arrangement may be such that the turbine I9 is situated at the extreme face end of the engine, as shown in Fig. 3 to the left, or else the blower 20 may occupy the exteriormost position at the face end of the engine, as
shown in Figs. 2 and 3 to the right.
According to the invention to each turbine l8 and IS the exhaust gases from the one part of each row of cylinders of the engine are led, in such a way, that in the examples shown, half the number of cylinders of each row of cylinders exhaust separately for each row into the exhaust gas turbine l8, whereas the remaining half number-of cylinders exhaust separately for-each row into the exhaust gas turbine is. Therefore, not all the cylinders of"one row of cylinders dis: charge into one and the same exhaust turbine.
In order to provide for the exhaust puffs of the cylinders of diflerent rows not interfering with each other, particularly so that the scavenging operation in the individual cylinders is not frustrated, the exhaust gases from different cylinder blocks are passed into separate admission spaces ornozzles of the respective turbine, said admission spaces being separated from eachother by partition walls 22, shown in all the figures of the drawings. In Fig. 4, which represents a vertical longitudinal section through the axis of the internal combustion engine from which the two blowers i6, i1 have been omitted for the sake of clarity, the passage 23 15 shown to extend along the full length of the engine. The air is conducted into this passage through two upper .openings, as shown, one of which is visible in Fig. 1 also; The pre-compressed supercharging air delivered by the blowers and ii passes to the inlet valves I! of the engine through intercommunicating passages 23, 24, that are also situated within the V-shaped open space of the engine. Alternatively, the construction may be such that the frame of the engine itself or portions thereof form conduction means for the supercharging air, as shown in cross-section in Fig. i for the main duct or collecting space 23 of the intercommunicatlng passages.
The invention provides for a very advantageous arrangement of the conduction means for the exhaust gases and the supercharging air, as it is simple and symmetrical and thus easy to inspect.
By virtue of the arrangement of a supercharging air conducting system intercommunicating with all thecylinders of the engine the sup- By disposing the conducting means for the superchamins air within the open V-shaped space or the engine frame the conduction oi this air. to the numerous cylinders is considerably simplified, while at the same time these means are completely separated from the hot exhaust conduits and are positioned against the water cooled jackets oi the engine so that the compression heat of the charging air is taken up by the water Jacket.
I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described, all of which may be varied without going beyond the scope oi my invention as shown, described and claimed.
What I claim is:
1. In a supercharged multi-cylinder internal combustion engine, two rows of cylinders arranged in blocks forming a'V, water cooled jackets around said rows of cylinders, a turbo-blower unit disposed in said V at an end thereof with the turbine thereof outermost so as to be accessible to the operator for inspection and care, exhaust pipes irom the exhausts oi the cylinders oi said engine to the turbo-blower, and a common supercharging air conduit supplying air from the blower to the cylinders, said conduit comprising a jacket'on the inner races oi the cylinders within the V, the water cooled jackets lying between the turbo-blower and exhaust pipes and the engine cylinders, and in contact with the supercharging air Jacket.
2. In a supercharged multi-cylinder internal combustion engine, two rows 0! cylinders arranged in blocks and forming a V, water cooled jackets on the inner faces of the rows of cylinders, a pair 01' turbo-blower units utilizing the exhaust gas of the eng'ine and supplying compressed air for supercharging the engine cylinders, said units being located in the V and each at one end thereof, conduits connecting the exhaust openings oi the cylinders with the turbo compressors, and a casing covering the in'ner
